SNARE-WEAR-RELIEVING DEVICE.

Application filed May 9,

This .invention relates to a simple device for relieving the wear of the snares of a drum on the skin head, especially where the snares pass over the edge of the skin head.

An object of the invention is to provide a simple, efficient and durable attachment which can be applied to any form of drum employing snares and which can be very quicklyA applied without involving any particular alteration in the construction and arrangement of the parts already on a drum of this type.

The inventionis illustrated in the drawings, of which-e Figure 1 is a partial plan view of the device attached to the rim of the drum;

Fig. 2 is an elevation looking at the device from the inner sidevof the drum;

Fig. 3 is an elevation looking at the device from the outside of the drum;

Figfl is a section taken on the line 4 4 of Fig. l;

Fig. 5 is a section taken on the line 5-5 of Fig. 1; and

Fig. 6 is a modified section showing a modified form of the idea.

The form of the invention shown in the drawings is a preferred form, although it is understood that modifications in the construction and arrangement of the parts and in the characters of the materials used may be adopted without departing from the spirit of the invention as set forth in the appended claims.

In developing the invention it was my idea to provide a simple and efficient little attachment which could be applied to any sort of snare drum adjacent the snare opening iu the rim, and to provide this rim plate with a release bearing, over which the snares would pass at a point adjacent the edge of the skin head so that the wear and` weight of the snares would be taken by the bearing and would be relieved from the skin head so that the skin head would not wear out quickly, as is always the case where the snares pass over the edge of the skin head and are continually being tightened and released to produce different effects with the drum. l

It is, further, my idea to provide means whereby the rim-engaging plate could be adjusted with respect to the level of the skin head for different types of drums, so that the release could be quickly and easily ad- 1924. Serial No. 712,073.

justed with respect to the plane of the skin h'ead to properly receive the snares.

It is further contemplated to provide a simple resilient member attached to the rear of the rim-engaging plate to bear :z

lightly on the rim so as to insure a certain amount of frictional engagement between the rim and the attachment to hold it in place and to provide means for varying this friction, and to accommodate thicknesses of drum rims.

The preferred form of the invention shown in the drawings comprises a plate 1 having U-shaped portions 2 and 3 t-o extend over the rim 4 of a drum. This plate is provided with an opening or cut-away portion 5 adapted to be disposed opposite the snare opening 6 in the rim. Disposed in this opening 5 is a roller bearing 7. This bearing is adapted to receive the snares 8 which pass thereo'ver. These snares at their outer ends are connected to any suitable member 9, which enables the tension on the snares to be adjusted in the well known manner. Across the outside of the rim of the drum is disposed a spring plate 10 adjustably connected by nuts 11 and 12 to the U-shaped portions 2 and 3 of the plate 1. The ends 13 and 14 of this spring plate are curved inwardly to bear against the rim. By adjusting the set screws 11 and 12 the degree to which the ends of this spring member bear against rim can be adjusted.

The inner ends of the plate 1 are provided with horizontally extended flanges 16 and 15 which are bored to provide for the passage of adjusting nuts 17 and 18. These nuts bear on foot plates 19 and 20. These foot plates are adapted to rest on the skin head, and have vertically extending portions, such as represented by the numeral 21 in Fig. 5, extending up between the plate 1 and the rim. These upwardly extending portions are provided with laterally bent ears such as 22 which embrace the U-shaped members 2 and 3. One of the ears embraces the edge of these U-shaped members. The other of the ears passes through a slot such as 23 formed in the U-shaped members 2 and 3.

This construction provides means whereby the foot plates can be slid up and down on the rim-engaging plate or rear means, whereby the rim-engaging platecan be adjusted vertically with respect to the foot different plates which always rest on the skin head, and in this manner the level of the release can be adjusted so that the snares 8 in passing' over the release Will not bear very heavily on the edge or the skin head as it is bent dowi'iwardly. ln this way the Wear ot tha snares is taken onf the edge of the skin head and berne by the release.

'it will thus be observed that l have provided a simple and etlicient device which can be attached to the rim of any snare drum, which can be quickly adjusted to the proper position relative to the skin head and to the shares, and riotionally adjusted on the rim to the desired degree with a minimum of effort on the part of the operator.

ln Fig. G instead ot providing the foot plates l merely extend the rim-engaging plate downwardly to the level of the skin head and flange it out as shown at 24 to rest on the skin head. This is of course possible VWhere'the device is to be yapplied to a particular type of drum, where the depth between the top of the rim and the surface ol` the skin head is a deiinite distance.

lVliat l claim is i l. A device for relieving the Wear of snares of drums on the drum skin head, which comprises a member clamped `to the rim of a drum, an adjustable bearing on said member over which the snares pass, and means for adjusting said bearing with respect to the plane ofv the skin head, said bearing on said member lying outside the periphery of the drum.

2. A snare-Wear relieving device for drums, which comprises a plate embracing the rim of a drum, .means resting on the skin head of thedrum, means connecting the plate and said iirst-mentioned means 'for adjusting the position of the plate with respect to the skin head, and a rotatable bearing member carried by the plate, the snares of the drum passing over the rotatable bearing member near the edge of' the assai-iai.

skin head to eliminate the Wear of the snares on the skin head at the edge ofthe drum.

3. A snare-Wear relieving device for drums, which comprises a U-shaped plate `slipped overthe ,rimof a drum, a roller for adjusting the relative position between the rmi-engaging plate and the foot plates.

4. A snare-Wear relieving device for drums, which comprises -a U-shaped plate slipped over the rim of a drum, a roller mounted on said plate and disposed inthe snare opening oi' .the rim, a Vpair ot' lfoot plates adjustably connected to theinner side of the rim-engaging plate, said foot plates resting on the Skinhead, means for adjusting `the relative position 'between the rimengaging plate and the foot plates, and spring means attached to the rear of the rim-engaging plate andadjustable With respect thereto, said spring means 'bearing againstV the rim tovary the degree to Which theplate is held on'the rim.

5. A snare-Wear ,relieving device for drums, which comprises a `U-shaped plate slipped overthe rim of a drum, a roller mounted on said plate 'and' disposed in the snare opening of the rim, a pair ofyfoot plates adjustably lconnected to the inner side olf the rim-engaging plate, said foot plates resting on the skin head, means for ladjusting the relative positionibetvveen the rimengagingplate andthe foot,plates, a spring plate extending across the rear of the rimengaging plate, the ends of the spring plate bearing against the rim `beyond the ends oi" the rim-engaging plate, and adjustable Vmeans connecting the spring plate with the rim-engaging plate to vary the tension of the spring plate on the rim.
